KGZN-OL Power Quality Monitor Electric Energy Power Meter Power Quality Analyzer ISO9001
Product Introduction
KGZN-OL power quality monitor is a high-end power quality monitoring device for high-end users jointly developed by a number of senior developers and designers, combining our company's many years of research and development experience in power quality monitoring equipment and user needs.
KGZN-OL power quality monitor follows the latest seven national standards of power quality, adopts FPGA+ embedded 104 industrial control board core, multi-piece 16-bit 6-channel high-precision synchronous A/D converter design, It integrates comprehensive steady-state and transient power quality monitoring and analysis, high-precision measurement, ultra-long time event recording, internal statistics, ultra-large capacity storage, GPS satellite timing, on-site print-out, PQDIF, IEC61850 and many other functions, creating a first in the simultaneous monitoring of multi-loop power quality transient events. Become one of the most advanced power quality monitoring devices in China.
KGZN-OL Power Quality Monitor Electric Energy Power Meter Power Quality Analyzer ISO9001
Product Characteristics
1, using FPGA+ embedded 104 industrial control board core, seamless data acquisition. It realizes the organic combination of high performance and low power consumption.
2, ultra-long time recording function: can record a maximum of 420 cycles, that is, 10 cycles before the event, 10 cycles after the event, 400 cycles during the event process (8 seconds).
3, real-time internal statistical function: to achieve the real-time statistical function of the device, while storing the maximum value, minimum value, average value, instantaneous value. The defect that the device can only store the current value is changed in the past, so that the measured data is more real and effective.
4, ultra-large capacity SST solid state storage disk storage: industrial grade 60G solid state storage disk storage data, a separate transient data storage area, transient data storage capacity is larger, and steady state data does not interfere with each other.
5, each loop uses an independent A/D converter, which is the first time in China to realize the simultaneous monitoring of multi-loop power quality transient events and waveform recording.
6, support data U disk export and field printer: the device has two USB interfaces, which can export data to the U disk, and can be used as an interface for device upgrade, and support field printer print output function.
7, support GPS B code timing.
8, at the same time support PQDIF and IEC61850 two data formats.
KGZN-OL Power Quality Monitor Electric Energy Power Meter Power Quality Analyzer ISO9001
Product features:
1, can seamlessly monitor and analyze all power quality parameters of all voltage and current points: Harmonic voltage, current (2-65 times), interharmonic, frequency, voltage deviation, voltage fluctuation and flicker, three-phase unbalance of voltage and current, phase Angle, harmonic total active power, harmonic phase Angle, harmonic impedance, (negative sequence, positive sequence, zero sequence) current, total power, apparent power, active power, reactive power, power factor and other parameters
2, with voltage surge, voltage drop, voltage short-time interruption, power quality superstandard wave recording, manual wave recording.
3, equipped with 6.4 inch 640*480 true color LCD screen, in a variety of forms to show power quality: With real-time data (maximum value, minimum value, average value, instantaneous value), waveform, spectrum, vector diagram, transient analysis waveform display, log and other forms, measurement data can be displayed, printed, saved, U disk export, upload, etc., storage format compatible with WINDOWS.
4. Transient trigger and analysis function
(1) Including voltage dip, voltage rise, short time voltage interruption events, data records include events
(2) After the event occurs, the monitoring device records the waveform of all voltage and current channels. Automatic or manual trigger recording can be set.
(3) The power quality trigger setting can be set to record and reproduce the transient waveform before and after the power quality exceeds the limit.
(4) It can automatically find the starting point of sudden rise and sudden drop, and display the starting time, duration and depth of sudden rise and sudden drop;
(5) Waveform recording can record a maximum of 420 cycles, that is, 10 cycles before the event, 10 cycles after the event, and 400 cycles during the event process (8 seconds).
